This will be needed by the layout node, which may change what is painted
when the position of the frame image is not the same as the element's
current time.
Note that the default value of the attribute is true. We were previously
autoplaying videos as soon as they loaded - this will prevent that from
happening until the paused attribute is set to false.
It's not totally clear to me when all of these states are supposed to be
set. For example, nothing in the HTMLMediaElement spec says to "set the
readyState attribute to HAVE_ENOUGH_DATA". However, this will at least
advance the readyState to HAVE_METADATA, which is needed for other
useful attributes for debugging.
The spec for loading a media element is quite huge. This implements just
enough to parse the attribute, fetch the corresponding media object, and
decode the media object (if it is a video). While doing so, this also
implements most network state tracking and firing DOM events that may be
observed via JavaScript.
Note that as of this commit, there aren't any such throwers, and the
call site in Heap::allocate will drop exceptions on the floor. This
commit only serves to change the declaration of the overrides, make sure
they return an empty value, and to propagate OOM errors frm their base
initialize invocations.
This needs to happen before prototype/constructor intitialization can be
made lazy. Otherwise, GC could run during the C++ constructor and try to
collect the object currently being created.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This is a monster patch that turns all EventTargets into GC-allocated
PlatformObjects. Their C++ wrapper classes are removed, and the LibJS
garbage collector is now responsible for their lifetimes.
There's a fair amount of hacks and band-aids in this patch, and we'll
have a lot of cleanup to do after this.
We had some inconsistencies before:
- Sometimes "The", sometimes "the"
- Sometimes trailing ".", sometimes no trailing "."
I picked the most common one (lowecase "the", trailing ".") and applied
it to all copyright headers.
By using the exact same string everywhere we can ensure nothing gets
missed during a global search (and replace), and that these
inconsistencies are not spread any further (as copyright headers are
commonly copied to new files).
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

This was done with the `ambr` search and replace tool.
